In the documentation to the "Export" function it says that
"Machine-precision numbers are by default written to six-digit precision".
If I try:
z = {{Pi, 2 Pi}, {10, 100.}} // N
{{3.14159, 6.28319}, {10., 100.}}
Export["z1.dat", z]
I get the file "z1.dat":
3.141592653589793 6.283185307179586
10. 100.
This is not 6-digit precision. Is there a way to specify the precision that the
"Export" function should use?
